表面漆对地板材料火灾初期热释放特性影响的研究

漆与木材是两种不同性质的材料，带有表面漆和不带表面漆的木地板在火灾初期的热释放特性有所不同。本文利用锥形量热计对不同辐射能量条件下的两类木地板的释热特性了实验研究，发现漆对木地板的点燃性和点燃初期的释热特性有较大的影响。这种影响与木材的种类和外部辐射能量的大小有密切的关系。

Study on The Effects of Flooring Heat Release Characteristics at Initial Burning Stage Caused By Surface Lacquer

Lacquer and wood are two different materials,so there are some differences between heat release rate characteristics of surface painted wooden floors and non\|painted wooden floors at initial burning stage. Two kinds of floors were tested at several radiant heat flux levels by Cone Calorimeter in this paper. The test results showed that lacquer had great impact on floors' ignitability and heat release rate characteristics in initial burning stage. The impact has close relationship with the breeds of wood and the outside radiant heat flux.
